Title: Removable magnetic data storage system
IPC: G11C17/02
Filed: 1967-08-31
Abstract: 1,147,112. Magnetic storage arrangements. SPERRY RAND CORP. 31 Aug., 1967 [22 Nov., 1966], No. 39949/67. Heading H3B. A storage matrix has a replaceable sheet of magnetic storage material, the arrangement enabling selected information storage patterns to be physically inserted or removed from the store as required. The information registered in a given sheet may be either read out non- destructively or replaced by fresh data by appropriately energizing the matrix conductors. The matrix, Fig. 3, consists of row conductors 31-35 each coated with high permeability magnetic material and orthogonal drive straps, the row conductor coatings being each slit longitudinally, Fig. 2, so as to provide an air gap 17. The storage sheet 19 is positioned adjacent the air gaps and consists of a magnetizable substrate with a coating 20 of iron oxide. A magnetized storage region 21 in the storage sheet produces a circumferential flux in the adjacent part of the coated conductor, as shown, with the flux direction dependent on the binary digit stored. For non-destructive readout, the circumferential flux is disturbed by a longitudinal flux 27 produced by pulsing a selected drive strap, and two successive output pulses of opposite polarity are induced in the coated conductor. For writing new data, the coated conductor 11 is pulsed in an appropriate direction and so establishes storage fields at those locations where the drive straps are not energized by an inhibiting current. Reading and writing control is effected by electronic data processing equipment 41 in association with a bi-directional write signal generator 40, gates 37 and a drive strap selector. Additional coated conductors 71, 74 and drive straps 73, 75, 76 are provided for detecting correct location of a replacement storage sheet with respect to the matrix conductors, the storage sheet being provided with a horizontal and a vertical magnetized strip (67), (78) for the purpose, Fig. 4 (not shown). Location in the vertical sense is obtained by moving the sheet vertically with respect to the conductors until A.C. applied to drive strap 50 from a location control and display unit has maximum coupling with coated conductor 71. Tilt is then determined by pulsing drive straps 49, 50, 51 in turn. The process is repeated for horizontal alignment using coated conductor 74 and drive straps 73, 75, 76. Details described include the partial surrounding of the drive straps by a magnetic layer to improve magnetic coupling, Fig. 5 (not shown), and the provision of an insulating layer 24. Also the separation of the magnetic coating of each coated conductor into discrete portions each associated with a different storage region. The use of dummy coated conductors to reduce noise is also described, Fig. 7 (not shown).

Abstract: 1,130,090. Stoppering. ANCHOR HOCKING GLASS CORP. 13 Sept., 1966 [12 Oct., 1965], No. 40836/66. Heading B8T. A stoppering machine for applying caps 7 fed down as hoot 9 to bottles &c. 2 has a guide shoe 3 engaged by the caps and including a vacuum holding area 18 which keeps the caps level at the beginning of the application process. The vacuum holding area 18 is formed by holes 19 in the lower face of the shoe 3, which is hollow and is connected through a flexible pipe 24 to a Venturi pump 25. A hood 6 into which the bottles &c. 2 are passed is fed with steam through a pipe to which the Venturi pump 25 is joined. Thus a vacuum is produced within the hollow shoe 3, and the caps 7 are held against the underface of the shoe. The steam in the hood 6 replaces the air in the tops of the bottles &c. 2, so that when the caps 7 are secured in position, a vacuum develops within the bottles &c. as they cool. As shown, the bottles &c. 2 have threaded necks 21, and the caps 7 are screwed on to the necks by their engagement with two powered belts 22, one on each side of the caps (7), Fig. 2 (not shown).
